Targeting MRGPRX2: A Transformative Approach to Inflammatory Skin Conditions (ISDS 2025) - "Clinically, oral EVO756 suppressed icatibant-induced wheal formation in a phase 1 trial, confirming its ability to inhibit MRGPRX2-mediated responses in humans. These findings establish MRGPRX2 as a master regulator of mast cell and sensory neuron activation, driving neurogenic inflammation in CSU, AD, and beyond. EVO756 offers a potential groundbreaking therapeutic strategy, delivering multipronged benefits by targeting key pathogenic pathways across inflammatory skin diseases and other chronic inflammatory conditions."

EVO756 is a novel MRGPRX2 antagonist that potently inhibits human mast cell degranulation in response to multiple agonists – potential treatment for CSU and beyond (ISDS 2023) - "EVO756 potently inhibited MRGPRX2-transfected CHO-cell activation upon stimulation with substance P, ciprofloxacin, compound 48/80, PAMP, or icatibant. We conclude that EVO756 is a potent antagonist of MRGPRX2 activation and can prevent degranulation of human mast cells derived from a variety of origins and different donors, in response to various MRGPRX2 agonists. EVO756 may prove to be an effective treatment for diseases caused by inappropriate mast cell activation, including chronic spontaneous urticaria."
